SINAMICS G120/G120P, CU230P-2: Closed-Loop Control of a tunnel/car park fan

  • Entry
  • Associated product(s)
Application description for the scripted commissioning of a SINAMICS G120 for the control of a tunnel/car park fan
In tunnels and car parks fans and ventilators are used to
  • suction harmful exhausts
  • supply fresh air

In standard operation the volume flow (air) can be closed-loop controlled depending on air quality. In manual mode a fixed fan speed can be adjusted via the motor potentiometer.

With the function “Hibernate Mode” the converter will be switched off if it is not required for process reasons. With the function “Staging” further fans can be powered up by contactors if a higher volume flow is required. Furthermore a fire operation can be selected. This mode will drive the fan in case of an emergency with an adjustable speed which is independent from the speed control. Fans for both directions of rotation can also be driven by a negative speed setpoint to transport the smoke in a specific direction. In addition to that in fire operation all faults which would not directly switch off the converter will be ignored. Concerning faults which would result in switch-off the converter will be switched on by its automatic restart function after acknowledging all faults.
